Tableau Software : Three different ways to build funnels in Tableau—and why

This approach is the most advanced, but it's not complicated if you want a filled funnel shape with steps differentiated by color.

Thanks to Adam's blog post I learned to draw a real funnel, but when I wanted to have a filled funnel shape, I struggled. This is when I found a post by Rajeev Pandey on Tableau Community. He suggests creating two calculated fields for each funnel stage or step, so I don't recommend this technique if you think that you may add a stage in the future; your dashboard will not detect the new stage automatically and you would need to add two calculated fields to detect the new stage.

1. Create two calculated fields for your first funnel stage.

2. Create the same two calculated fields for all your funnel stages. This is what my Measures pane look like when all the calculated field have been created:

3. Place all those measures on the same axis by using a blended axis. Place this new Measure Values field on the Columns shelf:

4. You may get this type of funnel if you don't turn off the Stack Marks option:

This is what it should look like after the Stack Marks option has been turned off:

5. Final touch: add a title and a label to each stage by adding an axis. Type directly in the Columns shelf 'max(1)', add labels, and use a dual axis (as we did during the second approach) to place the labels on top of your funnel. This is what it will look like (all the numbers displayed in this viz are fictitious):
